History
Haneo Station opened on 7 March 1971 on the Agatsuma Line in the town of Naganohara, Gunma Prefecture, 46.4 km from the line's opposing terminus at Shibukawa, and passed to JR East at the 1 April 1987 privatisation of Japanese National Railways. Built as a staffed freight-handling station, it lost freight service in 1982 and its remaining loading shelters by 2007, was absorbed into the Tokyo near-suburban Suica zone on 1 October 2014, and had its last unwired sidings removed in 2018. The unstaffed station now consists of a single embankment island platform reached by an underpass.

Notes
Haneo is the westernmost passing point on the Agatsuma Line, and although Naganohara-Kusatsuguchi remains the official limited-express transfer for Kusatsu Onsen, some routing apps quietly route Tokyo–Kusatsu travellers through Haneo because the connecting bus fare from this stop is fractionally cheaper.
